Product details

Triple open-drain buffer for automotive and industrial busses

Each of the three elements sinks up to 32 mA while the supply rail spans 1.65 V to 5.5 V, covering 1.8 V logic through legacy 5 V busses without a level translator. The open-drain output lets you wire-AND multiple signals or drive loads that need a pull-up to a different voltage than the logic supply.

Wide supply and temperature range

The 8-VSSOP package (2.30 mm width) fits tight PCB layouts where board space is at a premium.

Open-drain output: 32 mA sink, no source

The open-drain output sinks 32 mA per channel but does not source current — the load must connect to a pull-up resistor. This suits driving LEDs, relay coils, or level-shifting a signal to a higher voltage rail. The high-impedance state when the output is off lets multiple buffers share a common pull-up for wired-OR or wired-AND configurations.

Frequently asked questions

Is SN74LVC3G07QDCURQ1 automotive qualified?

Yes, it is part of the Automotive, AEC-Q100 series, qualified for automotive-grade applications including under-hood and cabin environments.

Does SN74LVC3G07QDCURQ1 have an open drain output?

Yes, the output type is open drain, sinking 32 mA per channel with no high-side drive.

When sourcing SN74LVC3G07QDCURQ1, what is the closest functional alternative?

The SN74LVC2G17QDCKRQ1 is a similar AEC-Q100 buffer in the same family, but it uses Schmitt-trigger inputs and push-pull outputs instead of open-drain, and has only two elements versus three.
